Briggs & Stratton PowerProtect+ 18kW - Commercial-Grade Home Security
18,000 Watts LP/NG | 993cc Vanguard® Engine | 7-Year Industry-Best Warranty
The Briggs & Stratton PowerProtect+ 18kW (Model 040757) is engineered to provide massive starting power in a residential package. Featuring a commercial-grade Vanguard® engine, this unit is built to start a 5-ton air conditioner effortlessly, eliminating the need to upsize to a larger, more expensive model. With the exclusive front-facing exhaust and integrated EnergyTrak™ monitoring, it offers a safer, smarter, and more reliable backup solution for your entire home.
Elite Engineering for Harsh Environments
Every detail of the PowerProtect+ 18kW is designed for longevity. The redesigned enclosure features DuraZen™ protection, utilizing robust angled louvers to keep out moisture and dust while minimizing vibration. For neighborhood-friendly operation, the Eco-Cise™ Weekly Test Mode runs a quick 16-second diagnostic, ensuring your generator is ready to perform while drastically reducing noise and fuel consumption compared to standard test cycles.
Best-in-Class Starting Power
Engineered with a massive 45 kVA motor starting capability, this 18kW unit handles high-demand appliances and large AC compressors without the power dips associated with lesser models.
Exclusive Front-Facing Exhaust
A unique design that directs hot exhaust gases AWAY from your home. This enhances safety, protects your landscaping, and allows for greater installation flexibility near the structure.
